Robinson et al. (2004) state that neither commitment nor OCB reflect sufficiently two aspects of engagement-its two-way nature, and the extent to which engaged employees are expected to have an element of business awareness, even though it appears that engagement overlaps with the two concepts. Rafferty et al (2005) also distinguish employee engagement and the two prior concepts- Commitment and OCB, on the ground that engagement clearly demonstrates that it is a two-way mutual process between the employee and the organization.
